The 2nd generation Nest Protect has an industrial-grade smoke sensor, and detects the poisonous carbon monoxide you can't see. It tests itself automatically over 400 times a day to help keep you safe for up to 10 years – without the chirping in the night.

Easy to fit
No wires. No electricity. It’s battery operated - place it on any wall or ceiling.
